About this project

What does Sealed Time Capsule add?

Time Capsule

Leave something for your future self, or for everyone on your server.

How it works

  1. Craft a Time Capsule and place it.
  2. Choose how it keeps time: real-world days or in-game days.
  3. Pick how long it stays sealed, from 1 to 365 days.
  4. Put in your items and written books, then seal it.
  5. Until time runs out, the capsule stays shut and can't be broken open. Right-click it to see how long is left.
  6. When the time is up, open it and find what you left behind.

Great for

  • SMP servers: bury capsules at the start of a season and open them together at the end.
  • Long survival worlds: write a note to yourself and read it 100 days later.
  • Creators: "opening our one-year time capsule" episodes.

Lightweight by design

  • Capsules never tick. Time is only checked when someone interacts with one.
  • Plain block model, no custom renderers or shaders.
  • No extra libraries (Fabric only needs Fabric API).

Real-world or in-game days?

  • Real-world days use the real clock, so they keep counting while the game or server is off.
  • In-game days count Minecraft days, so they only pass while the world is running.

Configuration

Edit config/timecapsule.properties to set the default time mode, the default and maximum number of days, and whether the whole server is told when a capsule opens.
